(the same measurement rule as awesome-made-by-russians )

It's hard to calculate project popularity so we use stars as a measurement. It's not quite fair, but it is what we have here on Github.

If you want to add project to this list, please, make sure that:

• [ ] The project was created by the developers born in Brazil
• [ ] The project can't be just an personal, experimental or sample project
• [ ] The project has more that 100 stars on Github
• [ ] One repository per PR/contribution - avoid conflict and simplify review

That's all for today! 😁
